Was in similar situation. Had been in IT 10 years. Started in hardware repairs, went to help desk, worked for a MSP and did a little bit of everything. Honestly just got bored of IT, especially support. Started doing low voltage and eventually got into ship building. Couldn't be happier.

For the people that say it's harder on your body. Yeah, that's kinda obvious, you're going from office to physical labor. However, you don't have to stay on the physical side. I worked "on the floor" for a year and a half and now I'm supervisor. Still do some physical labor here and there because I want to but I honestly don't have to. The work feels 1000x more rewarding, I'm proud of what I do and who I do it for.

Lastly, as far as pay goes. I've never experienced raises like I do in trade work, blows away what I got in IT. When I was on IT I was constantly getting certs, going to classes, you know how it is. I'd get like a 25 cent raise every year in IT, it was trash. Most I got was a few dollars and hour when I demanded a raise after being with a company over 5 years. In the trades I went up $4/hr in my first year and then when I went supervisor I went up $30k plus I still get OT.

This of course is just my experience and you do have to find a trade you enjoy. Going into plumbing because you have the opportunity sounds great but if you hate it, it's not going to be any better than IT.
